Quick and simple  but not good for production    in a view       request scheme                 http or https     request META  HTTP HOST        example com     request path                    some content 1     in a template      request scheme           request META HTTP HOST       request path      Be sure to use a RequestContext  which is the case if you re using render    Don t trust request META  HTTP HOST   in production  that info comes from the browser   Instead  use  CarlMeyer s answer

You can use    protocol         domain    in your templates to get your domain name

You can use request build absolute uri   By default  it will return a full path  But if you pass in a parameter like this  request build absolute uri       This would return the domain name

I think what you want is to have access to the request context  see RequestContext

If you use the  quot request quot  context processor  and are using the Django sites framework  and have the Site middleware installed  i e  your settings include these   INSTALLED APPS                  quot django contrib sites quot              MIDDLEWARE                   quot django contrib sites middleware CurrentSiteMiddleware quot                  then you will have the request object available in templates  and it will contain a reference to the current Site for the request as request site   You can then retrieve the domain in a template with        request site domain    and the site name with        request site name

The variation of the context processor I use is   from django contrib sites shortcuts import get current site from django utils functional import SimpleLazyObject   def site request       return            site   SimpleLazyObject lambda  get current site request            The SimpleLazyObject wrapper makes sure the DB call only happens when the template actually uses the site object  This removes the query from the admin pages  It also caches the result   and include it in the settings   TEMPLATE CONTEXT PROCESSORS                  module context processors site                In the template  you can use    site domain    to get the current domain name   edit  to support protocol switching too  use   def site request       site   SimpleLazyObject lambda  get current site request       protocol    https  if request is secure   else  http       return            site   site           site root   SimpleLazyObject lambda    0     1   format protocol  site domain

request get host    should protect against HTTP Host header attacks when used together with the ALLOWED HOSTS setting  added in Django 1 4 4   Note that    request META HTTP HOST    does not have the same protection  See the docs   ALLOWED HOSTS A list of strings representing the host domain names that this Django site can serve  This is a security measure to prevent HTTP Host header attacks  which are possible even under many seemingly-safe web server configurations      If the Host header  or X-Forwarded-Host if USE X FORWARDED HOST is enabled  does not match any value in this list  the django http HttpRequest get host   method will raise SuspiciousOperation      This validation only applies via get host    if your code accesses the Host header directly from request META you are bypassing this security protection    As for using the request in your template  the template-rendering function calls have changed in Django 1 8  so you no longer have to handle RequestContext directly  Here s how to render a template for a view  using the shortcut function render    from django shortcuts import render  def my view request               return render request   my template html   context   Here s how to render a template for an email  which IMO is the more common case where you d want the host value  from django template loader import render to string  def my view request               email body   render to string           my template txt   context  request request   Here s an example of adding a full URL in an email template  request scheme should get http or https depending on what you re using  Thanks for registering  Here s your activation link     request scheme         request get host      url  registration activate  activation key

I know this question is old  but I stumbled upon it looking for a pythonic way to get current domain   def myview request       domain   request build absolute uri       -1        that will build the complete domain  http   foobar com

If you want the actual HTTP Host header  see Daniel Roseman s comment on  Phsiao s answer  The other alternative is if you re using the contrib sites framework  you can set a canonical domain name for a Site in the database  mapping the request domain to a settings file with the proper SITE ID is something you have to do yourself via your webserver setup   In that case you re looking for   from django contrib sites models import Site  current site   Site objects get current   current site domain   you d have to put the current site object into a template context yourself if you want to use it  If you re using it all over the place  you could package that up in a template context processor

Complementing Carl Meyer  you can make a context processor like this   module context processors py  from django conf import settings  def site request       return   SITE URL   settings SITE URL    local settings py  SITE URL    http   google com    this will reduce the Sites framework db call    settings py  TEMPLATE CONTEXT PROCESSORS                  module context processors site                 templates returning context instance the url site is    SITE URL     you can write your own rutine if want to handle subdomains or SSL in the context processor

Similar to user panchicore s reply  this is what I did on a very simple website  It provides a few variables and makes them available on the template   SITE URL would hold a value like example com SITE PROTOCOL would hold a value like http  or https SITE PROTOCOL URL would hold a value like http   example com or https   example com SITE PROTOCOL RELATIVE URL would hold a value like   example com   module context processors py  from django conf import settings  def site request        SITE PROTOCOL RELATIVE URL          settings SITE URL      SITE PROTOCOL    http      if request is secure            SITE PROTOCOL    https       SITE PROTOCOL URL   SITE PROTOCOL           settings SITE URL      return            SITE URL   settings SITE URL           SITE PROTOCOL   SITE PROTOCOL           SITE PROTOCOL URL   SITE PROTOCOL URL           SITE PROTOCOL RELATIVE URL   SITE PROTOCOL RELATIVE URL         settings py  TEMPLATE CONTEXT PROCESSORS                  module context processors site                SITE URL    example com    Then  on your templates  use them as    SITE URL        SITE PROTOCOL        SITE PROTOCOL URL    and    SITE PROTOCOL RELATIVE URL
